This species is characterized by its somewhat slender, apparently at least sometimes deciduous habit with the flowers and leaves clustered at the ends of lateral short-stems borne on sylleptic long-shoots; its triangular aristate stipules; its thin-textured, elliptic-ovate leaves with well developed pilosulous domatia and often a cordate base; its subsessile, fasciculate, several-flowered cymes; its pedicellate, five-merous flowers with well developed somewhat foliaceous calyx lobes; its hypocrateriform white corollas; its exserted stamens and fusiform stigmas that are shortly bilobed at the apex; and its rather small subglobose fruits. It has been collected at least sometimes on tsingy limestone. The petioles that are not articulated and the five-merous flowers indicate that this species may not be correctly classified in Ixora, but no other genus placement has yet been proposed; the classification of this species is currently under study by P. De Block (BR; pers. comm., Oct. 2013). Ixora malacophylla has flowers that resemble Tarenna, and is also similar in general aspect to species of Triainolepis, which has plurilocular ovaries and three or more stigmas.
